I tell you what, Splashin' Safari has a ton of visitors each year because they keep adding new attractions. Wildebeest and Mammoth have heavy lines all season long. Pilgrims Plunge is a great ride, but the splashdown effect is hardly new. Actually you kind of hit the water and get a wall of water dumped on your lap (that is if you are sitting in the front seat). I hate the heights and open-ness of the ride (I am terrified of heights).
I would like to see more parks invest in bomb-bay type slides, looping slides and just more attractions in general. Indoor resorts are really hitting the mark on these as they can keep customers coming in year round and can justify such high expenses with newer and more proto-type attractions.
